6 Claims. r91. 131-10 1 This invention relates to binder transfermechanisms for cigar machines, its main object'being tb'provide improvedbinder transfer means, and the present application'constitutes adivision of my co-pending application Serial 243,799, filed December 3,1938, on which Patent No. 2,287,004 was issued June 16, 1942.

The binder transfer constructionis similarto that shown in my co-pendingapplication Serial No. 183,405, filed January 5, 1938, on which PatentNo. 2,316,828 was issued April 20, 1943, to have its head move in ahorizontal plane in transferring a cut binder from the cutting die tothe rolling apron, and is associated with a duplex die turret whichmakes a half turn after each die has been served and dwells while thecutter rolls sweep across the die. When a binder is to be transferredfrom one of the dies, the transfer head is positioned above the cuttingstation ofthe dies, the binder is raised into contact with the transferhead and-held by suction thereon as the head o'scillates'in a horizontalplane to a position a small distance above the rolling apron. Whenlocated in proper position over the apron, the transfer head descendsand the suction is out 01f, thereby depositing the binder on-the apron.Thereupon thetransfer head is againraised sufficiently to clear theapron and swung back to receiving position. Still another object of theinvention is to provide for adjustment ofthe binder transfer to permitthe binder to be deposited in the proper position .on the bunch rollingapron. a

.A further object is to increase the speed at whichbinders may betransferred from the binder die turret to the bunch rolling table;

thereby permitting the attainment of the maximum speed of binder cuttingwith the die turret and the operation of the bunch rolling table at themaximum speed. It will be noted that with the binder transfersheretofore in use the binder transfer head thereof has a parallel motionin an arcuate path extending over 180 degrees from the 'die to thetable, whereas the movement of the-present binder transfer has onlyapproximately a 45 degree are. lotted for the transferring of the binderis greatly reduced and the operation of .the machine speeded up.Moreover the binder die maybe placed close to the rolling table and thenecessary floor space and the size of the machine is reduced.

With these and other objects not specifically mentioned in view, theinvention consists in certain constructions and combinations hereinafterfully described and then specifically set forth in the claims hereuntoappended.

In the accompanying drawings, which form a part of this specificationand in which like char- EW EQQ .1 7..

Number Thus the interval a1- anism; a v V m; 'Fig. 3. is a sectionalviewon line 3--3 of Fig.

2; and "1 y i ,.Fig. 4 isa detail end elevation on line 4-4 of Referringto Fig. 1, the binder leaf is served :53 by an operator to one of the,dies of an intermittently revolving duplexdie turret H, such asdisclosed in my above mentioned Patent No. 2,316,828. After having madeone-half revolution, the, turret dwells and the binder B is cut from theserved leaf .by the rectilinear movement of the rollers I2, 13 acrossthe die vHi5. Upon the return of the cutting rollers into initialposition, the die head I06 -(Fig. 2,) ascends with the cut binder intocontact with the bottom face ofthe suction head M of the binder transferit, which at that time is in receiving position above the die. At themoment of contact, the suction in the diehead is cut ofi andsuction inthe transfer is turned on, thus transferring the binder from the ,die tothe transfer head and holding it thereon while the same is moved alongthe path it to its delivery position above the apron n of the rollingtable 18. The head is turned during this movement to assume the desired3511 oblique position on the roningapron, as indicated bythe path IQ ofthe wrist pin 18 connecting the transfer head to the connecting rod 86of bracket 83.

The binder cutting rolls l2, l3 are supported from a stud 20 (Figure l)carried by a bracket 21 attached to a Slide 22. The siide 22 issupported within a hollow rail 25 extending underne'ath the dieturrethead Hand fastened to the bed i i of the cigar machine by screwsre. The

ehds of therail 23 are closed by cappieces. 26

and the slide 22 is provided with a recess cornmunicating with an'oilgroove for lubrication of the bearihgsurfacesg The slide 722 has lugsv3a in'which is'pivoted a link 3| connected to an "arm 32 fulcrumed on ashait33 in the base of the machine." The arm 32 is connected by a link 3f with a bell [crank 35 .fulcrumed on a shaft 56 and having a roller 31in engagement with the I -=track of a cam 39 mounted on the cam shaft 46of the machine. v j

As the cam 39 revolves in the counterclockwise direction, the roller 31moves upwardly to a position whereby the bell crank 35 is swung upwardlymo ;.and -thereby through link 34 turning the arm 32 44 is clamped ateach end in a bracket 46, hav

ing bearings 41 mounted on stud 20 and connected by a bridge arm 48,thereby providing a box formation which imparts rigidity to the same;and the shaft 45 is similarly supported by a bracket 49 having bearings50 mounted on stud 20 and connected by an arm I. Between the bearings ofeach of theabrackets 46 and 49 there are adjustably fastened on stud 20collars 52 having hollow ends enclosing torsion springs 53 anchored atone end to the collar 52 and at the other to the adjoining bearing .ofthe respective bracket. Between the collar 52. and the non-tensionedbearing 50 of bracket 49, there is fastened to stud 20 an arm 54carrying stop screws 55 bearing on the bridge arms 48 and SI. By turningthe said screws'55, the collars 52 and thus'the height. of the rollers12, I3-and their tension against the die can be precisely adjusted tovarying conditions of operation. The construction of theshafts 44, 45and the manner in which they are supported, forms the subject matter ofmy co-pending application Serial No. 419,130, filed November 14, 1941,on which Patent No. 2,343,946 was issued and which is a division of myabove-mentioned application Serial No. 243,799 on which Patent No.2,287,004 was issued. The binder transfer is mounted on hollow column 56adjustablysecured to thebed 24 by screws 5'! passing through elongatedslots 58 in the latter and fastening to the underside of the bed abracket 59 having an upwardly extending hub portion 60 projectingthrough anoval-slot M in the bed into the base of the column 56.

Projecting fromand free to-turnin-a bushing 62 in the upper end-ofcolumn 56 is a vertical tube 63 which extends down throughthe hu'b60into a bushing 64 in a downwardly projecting yoke 65- of bracket 59.Into-thelowerendof bushing 64 isfitted atube 66 heldlinplace-bya clamp61 and connectedto asuction-chamber 68 in the bed of.the machine, thetube 66.being..provided withjoints permitting expansion. thereof .as.the column 56 is adjusted to a greater distance from the binder, die.

To the top end of tube;.63 is clamped a hollow transfer arm I5, which.at itsfree endcarries. t neck 6 of a suction head I4, the neck 6.9.being free to turn on and secured on arm, I5. by. a bolt Ifl having itshead mounted in the ball bearing" nd th ea ed intqan internal lu of theneck 69 to hold thesarne against theball bearing 12 of th m '5-,AsereenJ-i insert into the lower end of neck 69prevents lea Particlesfrom being sucked intothe transfer arm. The perforated suction plate I4of suction head I4 is made readily detachable for cleaning by providingit with slotted lugs engageable with,

the depressible 'con head of a spring-pressed bolt I5 at oneend'and'with' a fixed flat'head of abolt'16 at the other.-'

The neck 69 hasa'crankextension I! carrying a'crank pin 18 engagingwith'a socket I9 at one endof a connecting rod 80; the other end ofwhich has a socket 8'I pivoted toa pin 82 fastened in a bracket 83clamped to bushing62 in column 56. The connecting rod 80 'isso adjustedthat the suction head I4 is turned to'the desired angle as the arm I5carries it into-position-above the rolling apron I1.

Atsleeve 84 resting on the lowerhub portion 65 of yoke 59 is looselymounted on tube 63, this sleeve having an arm 85 Jcarrying aball-headedpin' 86 adjustable in a slot at its free end (Figs.

3 and 4). A boss 81 of arm 85 supports a post 88' on which is anchored aspring 89 attached to a post 90 in a boss .9I of a sleeve 92 clamped totube 63, the sleeve 92 having an arm 93 carrying at its free end anadjustable stop screw 94 arranged toencounter a stop plate 95 attachedto bracket59. The clamp sleeve 92 has a lug on which is rotatablymounted a roller 96 which is held against ashoulder formed on this lugand shown in dotted lines in Fig. 4, and roller 96 rests on a cam piece91 extending upwardly from the loose sleeve 84. This cam piece is shapedto permit movement of the roller 96 from an upper to a low r position,or vice versa, as relative,

swinging 'motionbetween the sleeves 84 and. 92 takes place. The campiece .91 has upward projections at the ends, providing positive stopsforv the roller 96 on reaching either level, thus preventing unduestress on spring 89 by moving the operating parts when the machine isnot in operation. v

On the b-all-headed-pin 86 is pivoted the socket 98 of a connecting rod99, the other end of which has a ball-and-socket joint I00 pivoted to acam lever I9I fulcrumed on shaft 33 and having a roller I02v inengagement with a track I03 of a cam I04 on cam shaft 40., As the rollerI02 is displaced by cam I04'from position. I92 to D0811- tion I02", thearm 85.0f the loose sleeve 84 is moved from position to 85",, carryingwith.

it, by the upward projection adjacent thehigh portion of cam piece 9]and shown engaging roller 96 in Figs. 3 and 4, theclamp sleeve 92,v

and thus turning the tube 63 and with it the transfer arm I5,from binderreceiving. position above the binder die. In position 85" of arm 05, thestop screw 94, having moved from position 94' to 94", engages with stopplate 95, thus arresting the clamp sleeve 92 so that the furtherdisplacement of cam roller I02 from position I02" to I 92" causes theloose sleeve to move alone from position 85'" to 85 against the pressureof spring 89, thereby turning the cam piece 91 and causing the roller 96to descend toits lower level. The tube 63 having been held in its upperor turning position by the resting of roller 96 on the high point of campiece9'I, the transfer arm I5 will therefore drop, bringing. the suctionhead I4 into contact with rolling apron II. By nowcutting offthesuctionin head .I4 and turn-. ing on suction in rolling table I8thr0ugh.-.mech+-.; anism of well. knownnonstruction, the binder is.transferred from th former to the latter; The. transfer arm I5 thenreturns to its starting. position for the next binder, being intransitraised to its upper position by the return motion of cam piece 91due to spring 89 as the cam I 04 brings roller I02 back into. positionI02" on the return stroke of cam lever I0I.

The relative verticalipositions of .the binder transfer andthe rollingtableand binder diear'e' shown in Fig-.2. In.the receiving position thecut binder is raised by the die head JOE-above the cutting edge of thedie-to the suction" plate I4, andinthe delivery'position it is loweredon-"tothe rolling apron I1; 7 r

The various adjustments described above are necessary to compensate forthe varying distances-- of the vertical axis of the neck of' diiferentsuc tion heads from the tube-63due to the difierent" locations of'theneck in-various suction headsgj It is necessary to maintain the suctionheadin a predetermined relation to the binder die which is supported ina predetermined position with its striking points I01, I08 inpredetermined relation to the path of the cutting rollers. Hence thescrews 51 are unfastened and the column 56 is adjusted to move thesuction head into the proper position above the binder die, and thethrow or angular displacement of the suction head is regulated to causeit to assume the desired position above the rolling table.
